I can't re-install Lion on my MacBook.

Put the Snow Leopard disc in the pc, then shut it down. After it is completely shut down, turn it back on and then hold down "C", until you see a "language selection" window, after that screen, you should have the ability to open Disk Utility (it is under one of the options in the menubar) and erase the internal drive.

Thanks Bob! And may I say that this forum is the best - very helpful advice, with reduced jargon for non-techies such as myself, and friendly members.
Very much appreciated.
We have liftoff - just waiting now for the OS to install, about 30 minutes.....
Many thanks.
